[0037] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0038] refer to Figure 1-5 and Fig.10The present embodiment provides a range hood, comprising a smoke collecting hood 1 and an opening and closing mechanism 2, wherein the smoke collecting hood 1 has an inclined smoke inlet surface (not shown in the figure), and an air inlet 121 and a mechanism disassembly and assembly port 122 are provided on the smoke inlet surface, wherein the mechanism disassembly and assembly port 122 is in a "T" shape with a large upper end and a small lower end, and comprises an upper mounting port and a lower mounting port, and the size of the lower mounting port is smaller than that of the upper mounting port. In the present embodiment, the number of the air inlets 121 is three, and the three air inlets 121 are arranged at intervals in the left-right direction, and an oil net assembly 8 is detachably installed at the middle air inlet 121; the number of the mechanism disassembly and assembly ports 122 is two, and the two mechanism disassembly and assembly ports 122 are respectively located on the left and right sides of the upper end of the smoke inlet surface. In addition, a switch maintenance port 10 is provided at the upper end of the smoke inlet surface. The switch maintenance port 10 is located between the two mechanism disassembly and assembly ports 122 and above the air inlet 121 and the oil screen assembly 8; lighting installation ports 123 are respectively provided on the left and right sides of the smoke inlet surface, and a lighting assembly 7 is detachably installed at the lighting installation port 123.

[0039] The opening and closing mechanism 2 includes a flap assembly 21, a fixed bracket 22 and a driving assembly 23. The flap assembly 21 is arranged below the smoke inlet surface and is used to open or close all air inlets 121, the lighting assembly 7 and the oil screen assembly 8. In this embodiment, there are two fixed brackets 22, and the two fixed brackets 22 are arranged in a one-to-one correspondence with the two mechanism disassembly ports 122. The lower end of each fixed bracket 22 is attached to the front of the smoke inlet surface and is detachably connected to the smoke inlet surface. Specifically, the lower end of the fixed bracket 22 is detachably connected to the smoke inlet surface by a fastener (such as a screw); the upper end of the fixed bracket 22 passes through the mechanism disassembly port 122 from bottom to top and extends into the smoke hood 1. In this embodiment, there are two drive components 23, and the two drive components 23 are arranged in a one-to-one correspondence with the two mechanism disassembly and assembly ports 122. Each drive component 23 can be movably inserted into the mechanism disassembly and assembly port 122, and is respectively connected to the upper end of the corresponding fixed bracket 22 and the flap component 21, so as to drive the flap component 21 to open or close the air inlet 121.

[0040] When the opening and closing mechanism 2 needs to be removed, since the fixed bracket 22 and the driving assembly 23 are configured to be able to pass through the mechanism disassembly opening 122, after loosening the fasteners connecting the fixed bracket 22 and the smoke inlet surface, the fixed bracket 22 and the driving assembly 23 can be directly disassembled downward from the smoke hood 1, so that the entire opening and closing mechanism 2 can be removed from the smoke hood 1, regardless of whether the flap assembly 21 is opened. When the opening and closing mechanism 2 needs to be installed, the upper end of the fixed bracket 22 and the upper end of the driving assembly 23 are first extended into the smoke hood through the corresponding mechanism disassembly opening 122, and then the lower end of the fixed bracket 22 is connected to the front of the smoke inlet surface of the smoke hood 1 through the fasteners. The flap assembly 21 can be connected and fixed to the driving assembly 23 before the fixed bracket 22 and the driving assembly 23 are installed on the smoke hood 1, or it can be connected and fixed to the driving assembly 23 after the fixed bracket 22 and the driving assembly 23 are installed on the smoke hood 1.

[0041] refer to Figure 3 and Fig.10 The fixing bracket 22 includes a lower mounting surface 221 and an upper mounting surface (not shown in the figure) which are fixedly connected. The lower mounting surface 221 is in the shape of a "7" with one end being large and the other end being small. The lower mounting surface 221 is attached to the front of the smoke inlet surface and is detachably connected to the smoke inlet surface. In this embodiment, the lower mounting surface 221 is detachably connected to the smoke inlet surface through three fasteners. The upper mounting surface extends from the bottom to the top through the corresponding mechanism disassembly opening 122 into the smoke hood 1 and is connected to the drive assembly 23 to fix part of the drive assembly 23 in the smoke hood 1. Therefore, after loosening the fasteners connecting the lower mounting surface 221 and the smoke inlet surface, since the lower mounting surface 221 is located outside the smoke hood 1, the lower mounting surface 221 can be directly removed downward, thereby driving the upper mounting surface to be removed downward from the smoke hood 1 through the mechanism disassembly port 122. Since the driving component 23 is fixed on the upper mounting surface of the fixing bracket 22, the driving component 23 can follow the upper mounting surface through the mechanism disassembly port 122 to be removed downward from the smoke hood 1.

[0042] refer to Fig.10The upper mounting surface includes a first flange 222 and a second flange 223 arranged side by side and spaced apart. The second flange 223 is formed by bending one side of the lower mounting surface 221 upward, and the second flange 223 is used to strengthen the strength of the fixed bracket 22 and to fix the driver 232 in the drive assembly 23. In this embodiment, the second flange 223 of the left fixed bracket 22 is higher than the second flange 223 of the right fixed bracket 22. The driver 232 in the drive assembly 23 is fixedly mounted on the second flange 223 of the left fixed bracket 22. Since the second flange 223 of the right fixed bracket 22 does not need to be installed with the driver 232, its length can be shortened, saving materials and reducing manufacturing costs. Of course, the second flanges 223 of the left and right fixed brackets 22 can also be designed to be equal in height, and the second flanges 223 of the left and right fixed brackets 22 are both fixedly mounted with the drivers 232. In this case, the two drivers 232 are synchronous motors. The first flange 222 is formed by bending upwards at the rear end of one side of the lower mounting surface 221 away from the second flange 223 , and the first flange 222 is used to connect to the push rod 231 in the driving assembly 23 .

The drive assembly 23 on the left side serves as the active side, and the drive assembly 23 on the right side serves as the driven side. Of course, the drive assembly 23 on the right side may also be configured to include a push rod 231, a driver 232 and a connecting rod 233. In this case, the structures of the drive assemblies 23 on the left and right sides are completely the same.

In this embodiment, the end of the push rod 231 away from the flap assembly 21 is rotatably connected to the first flange 222 of the fixed bracket 22, so that the push rod 231 can drive the flap assembly to rotate relative to the fixed bracket 22. The driver 232 is arranged in the smoke hood 1 and connected to the upper end of the fixed bracket 22. In this embodiment, the driver 23 is fixedly installed on the second flange 223 of the left fixed bracket 22. The opposite ends of the connecting rod 233 are respectively connected to the output end of the driver 232 and the middle part of the push rod 231. The driver 232 is configured to be able to pass through the upper mounting opening of the mechanism disassembly and assembly opening 122, and the connecting rod 233 is configured to be able to pass through the mechanism disassembly and assembly opening 122.
